Season chicken with salt and pepper.
In a large skillet, melt butter over medium-high heat and add chicken; cook for 5 minutes on each side, or until lightly browned.
Add mushrooms and cook for 2 minutes, or until they begin to soften.
In the meantime, combine Worcestershire Sauce, sour cream and dijon mustard in a small bowl; mix until completely incorporated and smooth.
Spoon dijon sauce over chicken and continue to cook for 2 to 3 minutes, or until heated through.
Remove from heat.
Transfer chicken and mushrooms to a serving plate.
Garnish with chives.
